  • Title:The AdS5×S5 supercoset sigma model from 4D Chern-Simons theory
  • Start Date/Time:2020-11-26 / 12:30
  • End Date/Time :2020-11-26 / 13:30
    • Speaker:Dr. Jun'ichi Sakamoto (National Taiwan University)
    • Place:Lecture Room A of NCTS, 4F, 3rd General Building, Nat'l Tsing Hua Univ.
    • Host:Prof. Chong-Sun Chu (NTHU)
    • Abstract:Recently, a unified picture to describe integrable systems has been established by Costello, Witten and Yamazaki. In the case of 2D integrable field theories, Costello and Yamazaki proposed that by starting from a certain 4D Chern-Simons (CS) theory, one can construct classically integrable field theories systematically by taking a meromorphic 1-form and adopting an appropriate boundary condition. In this talk, I will explain how the AdS5×S5 supercoset sigma model and its integrable deformations can be reproduced from a 4D CS theory by generalizing the procedure for the 2D principal chiral model developed by Delduc et al [arXiv:1909.13824].
      This talk is based on works (2003.07309, 2005.04950) with Osamu Fukushima and Kentaroh Yoshida in Kyoto University.
